Jack-fax machine

Jack is relaxing in a sauna in Russia. A cell phone goes off. Jack sees a Russian reach beneath his towel, get the cell phone and talk about important business. The same happens, seemingly, with every other Russian in the sauna: everyone seems to have a cell phone and some important business to run. After a while, only Jack has not had a phone conversation, and the Russians begin to look at him suspiciously. Jack, uneasy about being perceived as an outsider, excuses himself and goes to the bathroom. There, he stuffs his butt with toilet paper. Upon return to the sauna, one Russian remarks: “Sir, there seems to be some paper sticking out of your ass.” “Ah, thank you,” Jack responds, “that must be my fax!”
